Irrigation and suction system, in particular for laparoscopic surgery

摘要

The present invention concerns an irrigation and suction system, in particular for laparoscopic surgery, comprising an active control apparatus (100), provided with a reusable motor (101′) capable to be attached to and to operate a disposable pump (102), and a disposable handpiece (104) provided with two valves (1603, 1604) capable to be connected respectively to an output duct (813) from the pump (102) and to a suction line, the two valves being operatable (1603, 1604) for making respectively the pump (102) and the suction line communicate with an output nozzle (1607) of the handpiece (104), the nozzle (1607) being capable to support a probe (110), the apparatus (100) comprising controlling electronics means (20) for controlling electronics means (1501) for driving the motor (101′), the system being characterised in that it comprises interface means (1505, 16, 17, 112, 113) connected to said controlling electronics means (20) capable to select an operation mode of the motor (101′) between continuous mode, wherein the pump (102) delivers fluid in a continuous and uniform way, and pulse mode, wherein the pump flow rate switches between a minimum flow rate and a maximum flow rate with a switching period.
